This is slightly better location and more attractive to family.

@Clinton Cook, while I have not used the Sterling Vikrell products before (thanks for the introduction to them), I do like that that are homogeneously colored throughout and the price point is most certainly attractive.  

Due to the nature of the neighborhoods and level of renters that they attract, I am always at low risk as the people I will get consistently have high credit ratings and good incomes.

Flips in that neighborhood could also be attractive, but there's a low ceiling for the ARV.

For starters, if you want to attract higher offers from investors you are going to need to market it to investors and not tenants. 

I try to eventually fence my properties because it attracts more people that care about that kind of thing (and screens undesirable neighbors). 

There is nothing that takes into consideration the condition of the property, the neighborhood, locations, terms of sale (for instance there could be owner financing), and any amenities the home may have (pool, large lot, view, proximity to a local attraction, beach, next to a freeway, etc.) 

In mid-priced areas (not the cheapest, but not nearly the most expensive) I feel like they would attract a slightly more mature, and potentially longer term audience of tenants.

My question would be what type of clientele are you going to be trying to attract.

It all comes down to being able to effectively mange the property and attract stable tenants.
